    Error 0xc000000f at startup indicates Windows cannot access the boot files or system drive, typically because the Boot Configuration Data (BCD) is corrupted or the boot device reference is missing or incorrect.

    To repair this, use Windows Recovery Environment (WinRE) or Windows installation media and follow these steps:

    1. Boot to WinRE
      • If the Recovery screen offers F1 to enter Recovery Environment, use that.
      • If it does not work, boot from a Windows 10/11 USB/DVD created with the Media Creation Tool.
      • On the Install Windows screen, select Next > Repair your computer to open WinRE.
    2. Verify the OS disk is visible
      • In WinRE, select Troubleshoot > Advanced options > Command Prompt.
      • Run: 
             diskpart
     list disk
     list vol
      • Confirm the disk and volume that contain Windows are listed. If the OS disk is missing, this is a hardware/firmware issue and requires OEM support.
    3. Check and repair the disk and system files
      • In the same Command Prompt (after exit from diskpart): 
             chkdsk /f /r C:
        (replace C: with the Windows volume letter shown by list vol if different).
      • After chkdsk completes, run: 
             sfc /scannow /offbootdir=C:\ /offwindir=C:\Windows
        (adjust drive letter if needed).
    4. Verify Boot Configuration Database (BCD)
      • Still in Command Prompt, run: 
             bcdedit
      • In the Windows Boot Manager and Windows Boot Loader sections, confirm that device and osdevice point to the correct system partition and that the path points to the Windows boot loader file. If these entries are missing, unknown, or point to the wrong drive, rebuild the BCD using standard WinRE bootrec/bcdboot procedures.

    If the BCD is repaired and the disk is healthy but the system still shows 0xc000000f, the issue can be a missing or corrupted critical system binary on the OS disk. In that case, restoring from a system image, performing a Reset this PC from WinRE, or reinstalling Windows from installation media is required.

    Are you able to force your PC into the recovery environment using these steps.

    Start your PC, just as Windows attempts to load (spinning dots), press and hold Power Button for 5 - 10 seconds to perform a Hard Shut Down

    Do this twice

    On the third start Windows will boot into the Recovery Environment and from there you can access System Repair, Safe Mode, Command Prompt . . . etc.

    Please try each option one at a time, then see of Windows will boot up correctly.

    1

    If there is an option to uninstall the latest update, that may be the best otpion.

    2

    Go to Troubleshoot - Advanced Option - Startup Repair

    See if Windows startup can repair itself

    3

    Go to Troubleshoot - Advanced Option - System Restore

    Check to see if you have a restore point you can go back to
